HENRY CUTTING, OF BUFFALO, NEW YORK.

POWDER AND LIQUID DISTRIBUTING DEVICE.

SPECIFICATION forming part of Letters Patent No. 773,852, dated November1, 1904.

Application filed September 14, 1903. Serial No. 173,021. (No model.)

To all w/wnt it may concern.-

Be it known that I, HENRY CUTTING, a citizen of the United States,residing at Buffalo, in the county of Erie and State of New York, haveinvented new and useful Improvements in Powder and Liquid DistributingDevices, of which the following is a specification.

This invention relates to a device or machine for distributing powdersand liquids, and is more especially intended for blowing powdered andliquid insecticides into cracks, crevices, and other inaccessible placesin buildings, vessels, cars, &c., to exterminate insects and vermin.

The object of the invention is to provide an efficient device of thecharacter described of simple and practical construction whereby eitherpowdered or liquid material, or both, can be thoroughly and evenlydistributed or blown in a continuous steady stream, spray, or currentand the force of the flow and quantity of material distributed regulatedat the will of the operator.

In the accompanying drawings, consisting of two sheets, Figure 1 is anelevation of a powder and liquid distributing device embodying theinvention. Fig. 2 is a top plan view thereof. Fig. 3 is a transversevertical sectional elevation, on an enlarged scale, of thepowder-receptacle. Fig. 4 is a fragmentary sectional elevation of theupper portion of the powder receptacle and agitator in line 4 4,

Fig. 3. Fig. 5 is a horizontal section of the powder receptacle andagitator in line 5 5, Fig. 8. Fig. 61s a transverse vertical section,

on an enlarged scale, of the liquid-receptacle.

Like letters of reference refer to like parts in the several figures.

A A represent two upright air pump or compressor cylinders, which aremounted on a suitable base or frame 6, preferably at opposite sides ofan upright compressed-air reservoir or container C, which is alsomounted on the base or frame 6. The lower ends of the air-compressorcylinders are connected with the compressed-air reservoir and compressthe air therein by pipes cZ. Suitable check-valves (not shown) areprovided to retain the pressure in the reservoir.

E represents reciprocating pistons working in the compressor-cylindersand connected by piston-rods e to the opposite arms of a pumplever F,fulcru med at its mid-length on a pivot f, supported by suitablebearing-lugs rising from the top of the air-reservoir. The pumplever isprovided at its opposite ends with suitable operating-handles f.

G and G represent, respectively, powder and liquid receptacles or tanksmounted on the base or frame 6 for containing the powder and liquid tobe distributed. The powderreceptacle G consists of a powder supplychamber or hopper g, which is preferably cylindrical and provided withan inverted conical or tapering bottom, and a powder discharge chamberor throat g, arranged beneath the contracted lower end of thesupplychamber and communicating therewith. The discharge-chamberconstitutes a support for the supply chamber or hopper. Thesupplyehamber is provided with a removable cover or closure 9 of anysuitable form, whereby the powdered material may be introduced into thesupply-chamber.

H represents an air pipe or conduit which connects at its upper end withthe air-reservoir through a three-way coupling 7b and is provided with asuitable controlling-valve h. The lower end of the air-supply pipeconnects with an injector nozzle or pipe J, the contracted discharge endof which extends into the powder discharge-chamber. The injector nozzleor pipe J is externally threaded and screwed into a screw-threaded holein the wall of the discharge-chamber or is connected therewith in anyother suitable manner.

K represents a powder discharge pipe or tube, which is of largerdiameter than the discharge end of the injector-nozzle and extends intothe powder discharge-chamber with its inner open end surrounding theinjector-nozzle. (See Fig. 3.) The powder dischargepipe is free to slidein a hole in the wall of the powder dischargerchamber and is adjustabletherein toward and from the injeetor-nozzle in any suitable manner toregulate the supply of powder to the discharge-pipe. In the constructionshown the discharge-pipe is provided outside of the powderdischargechamber with a fixed collar or flange 70, which engages looselyin an annular groove in an adjusting-sleeve which is internally threadedand screwed on an externallythreaded boss on the wall of the powderdischarge-ehamber surrounding the discharge-pipe. The latter is movedtoward and from the injector-nozzle by screwing up or unscrewing theadjustingsleeve.

L represents a flexible powder-distributing pipe, which is connected bya suitable union Z with the outer end of the powder dischargepipe. Thedistributing hose or pipe is provided at its outer end, if desired, witha powder-distributing nozzle or device l', which may be of a formcalculated to best distribute the powder for any particular purpose. Thecompressed air discharging from the injectornozzle J sucks the powderinto the dischargetube from the discharge-chamber and blows the same outthrough the distributing pipe and nozzle with a force which can beregulated as desired by properly manipulating the controlling-valve itof the air-supply pipe H. The quantity of the powder discharged isregulated to a nicety by moving the dischargepipe toward or from theinjector-nozzle.

The powder-receptacle is provided with an agitating device for looseningor agitating the powder in the supply and discharge chamhers to preventthe same from caking or packing and clogging the discharge-chamber. Thisagitator, which is located in the powder-supply chamber, is preferablyconstructed as follows, (see Figs. 3, 4:, and 5:) M represents avertical agitator-shaft, which is journaled at its upper end inbearing-openings in a crossbar at, which is secured to and bridges theupper end of the supply-chamber, and a substantially U-shaped yoke orbar at, secured to and depending from the cross-bar. The lower end ofthe agitator-shaft has secured thereto or is formed with a loop 012?,which extends down into the upper portion of the powder discharge-chamber, and is preferably provided with bent or irregular side pieces.The agitator-shaft has secured thereto between the bearing-yoke and theloop at its lower end. a plurality of agitating bars or wires at. Thesewires are provided with upper and lower lateral arms, which are attachedto the agitatorshaft in any suitable manner, and upright portions, whichare corrugated or bent into irregular form. The upright portions of theagitating bars or wires are arranged at different distances from theagitator-shaft, so

as to thoroughly loosen and agitate the entire l mass of powder in thesupply-chamber, and one or more of the agitating bars or wirespreferably contact with or move in close proximity to the side andbottom walls of the powder-supply chamber to loosen any powder ad heringto such walls. The agitator is oscillated by suitable mechanism actuatedby the pump-lever F, for which purpose the shaft of the agitatorhasfixed thereto above its bearing-yoke a beveled gear-wheel a, meshingwith a beveled gear-wheel 02, secured to the coupling it.

inner end of a horizontal shaft 01?, which passes through and bears in ahole in the vertical wall of the supply-chamber and is journaled at itsinner end in a bearing Men the bearingyoke for the agitator-shaft. Theouter end of the horizontal shaft is provided with a rockarm a, Fig. 1,connected by a link a with the pump-operating lever F. When the pumplever is rocked or oscillated to actuate the pump-pistons, it oscillatesthe agitator. The oscillating agitator operates much more effectively inloosening and agitating the powder than does a rotary agitator, whichlatter has a tendency to propel and pack the powder down into thedischarge-chamber.

The liquid-receptacle Gr may be of any suitble form, and, like the thepowder-receptacle, preferably has a discharge-chamber or contractedthroat O and is provided with a removable cover or closure 0 of anysuitable character, whereby the liquid can be introduced into thereceptacle.

P represents an air-supply pipe or conduit, which is connected at itsupper end with the air-resermir above the level of the liquid in theliquid-receptacle through the three-way coupling 72 and is provided witha controlling-valve p. The air-supply pipe connects at its lower endwith an injector-nozzle 1), similar to the injector-nozzle J andextending into the contracted discharge-chamber of theliquid-receptacle,

Q represents a liquid discharge pipe or tube, which extends through thewall of the discharge-chamber, with its inner open end surrounding theinjector-nozzle, the dischargepipe preferably being adjustable towardand. from the injector-nozzle in substantially the same manner as thedischarge-pipe for the powder to regulate the amount of the liquid.discharged. The liquid discharge-pipe is, however, preferably surroundedby a stuffingbox 9, which prevents leakage. The outer end of the liquiddischarge-pipe is connected by a suitable union 9* with a flexibledistributing pipe or hose R, provided at its outer end with anatomizing-nozzle consisting of a liquid-discharge tube 1'', having alateral discharge-orifice and provided with a regulatingvalve 9' of anyusual or suitable construction, and. an air tube or nozzle 0", connectedby a flexible air pipe or hose S with the three-way The air-pipe S isprovided with aregulating-valves, Fig. 1. The dischargeoriiice ofthe-air-tube r is arranged adjacent -to the discharge-orifice of theliquid-tube in such a manner as to direct the current of air across thedischarging jet of liquid and break the latter up into a line spray ormist, as in the case of an ordinary atomizer. The force and quantity ofthe liquid discharged can be regulated as desired by turning the valve pin the air-supply pipe P and adjusting the liquid discharge-pipe towardor from the injectornozzle p, and the liquid can be discharged in of thevalves it 1).

the form of a stream or spray of any desired force and proportion ofliquid and air by properly manipulating the valves 4- and s in theatomizing-nozzle and air-pipe S.

In operation of the machine the pumps A A are actuated by reciprocatingthe lever F and air compressed into the air-reservoir C. Either powderor liquid, separately or both simultaneously, can be distributed byproperly setting the valves it and p in the air-supply pipes H and P,leading to the powder and liquid receptacles, and the flow of either orboth can be stopped by closing either or both As the air for blowing thepowder and liquid is taken from the practically constant source ofpressure inthe airreservoir C, the material is delivered in anuninterrupted or continuous jet, which can be nicely regulated, asbefore explained, and as the air which is led to the powder-receptacledoes not come in contact with the liquid it is dry and has no tendencyto moisten and cake the powder, thereby interfering with its properdistribution.

The apparatus described is portable and of comparatively small size andfor convenience in operation is preferably placed on a suitable stand orframe, (indicated at T,) which, however, forms no part of the invention.
